Java and Android Tutorials By Surya Sir

Learn SOLID Design Principles - Interface Segregation Principle (ISP), Object-Oriented Design. ISP states that no client should be forced to depend on methods it does not use, promoting small, focused interfaces instead of large, unwieldy ones.

We’ll start with a problematic code example that violates ISP, showing you how large interfaces lead to confusion and maintenance issues. Then, we’ll walk through the process of refactoring the code, applying ISP to split the large interface into smaller, more cohesive ones that better align with client needs.

Part of Low Level System Design - Everything is explained in Hindi (हिन्दी)

What you'll learn:

What is the Interface Segregation Principle?
Common issues caused by violating ISP.
How to refactor your code to follow ISP.
Benefits of ISP for maintainability, scalability, and unit testing.
Real-world Java examples demonstrating ISP in action.

Interface Segregation Principle (ISP)-
Class should not be forced to implement interface that it does not use.
Instead of deigning 1 or 2 FAT interface design multiple interfaces.
It is the extension of single responsibilities.

One interface should not be handling a lot of responsibilities . Instead , multiple interfaces should be handling different responsibilities.

Design an interface in such a way that the classes that implements those interface does not have many unused methods.

Rule -
Always to have small and focused interface .

In this video, we break down the Liskov Substitution Principle (LSP) from the SOLID principles using a Java example. 📖 You'll learn:
✅ What the Liskov Substitution Principle is.
✅ A problematic code example violating LSP.
✅ How to refactor the code to follow LSP.
✅ Issues solved by applying LSP.
✅ Benefits for maintainability, scalability, and unit testing.
✅ Real-world application of LSP in Java development.
